VALVE AND VALVE-ACTUATING MEANS.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed August 23, 1909. Serial No. 514,183.

To all wlw/m 'it may concern:

Bc it lmoivn that I, CHARLES J. SIDDALL, u citizen of the United States,residing` at the city of Kalamazoo, county of Kalamazoo, State ofMichigan7 have invented ce1-tain new and useful Improvements inlValvesand Vi-Llve-Actuating Means, of which the following is a specification.

This invention relates to improvements in valves and valve actuatingmeans.

The main objects of this invention are:` First, to provide an improvedvalve and means for actuating the same, whereby the same may be actuatedfrom a distance. Second, to provide an improved valve mechanism for gasburners having a flash pilot in which the pilot flashing valve Willautomatically close While the main burner valve remains open untilclosed through the actuating means. Third, to provide an improved valvemechanism embodying these advantages which is very simple and economicalin strilcture and one which is not likely to get out of repair in use.

Further objects, and objects relating to structural details Willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the j following specification.

' The structure described constitutes one effective embodiment of myinvention. Other embodiments would be readily devised by those skilledin the art.

The invention is clearly defined and pointed out in the claims.

A structure constituting an eective and preferred embodiment of thefeatures of my invention is clearly illustrated in the accompanyingdrawing', forming a part of this specification, in which:

Figure 1 is a detail side elevation of a structure embodying thefeatures of my invention, the pneumatic actuating means being shown invertical section. Fig. 2 is an enlarged detail vertical section throughthe gas valve, taken on aline corresponding to line 2-2 of Fig. 1. Fig.3 is a detail vertical section, taken on a line corresponding to line 33 of Fig. 2. Fig. l is a horizontal section takeny on a linecorresponding to line 4&4 of Fig. 2. Fig. 5 is a vertical section of amodified construction in which the pilot flashing feature is omit-ted.Fig. 6 is a vertical section of another modification in which the valveproper is formed separately and attached to the valve diaphragm, thevalve here shown is adapted for an inverted burner.

In the drawings, similar reference characters refer to similar partsthroughout lthe several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the gas supply pipe, the samebeing shown in the form of a Wall bracket. The burner 2 which isillustrated as the common form of open burner is preferably mounted onthe gas valve casing 3, which is connected to the supply pipe by meansof the nipple 4, having the supply passage 5 therein. The pilot burner 6is mounted upon the valve casing 3. The main burner is connected to thevalve chamber 12, by the passage 7, While the pilot burner is connectedto the valve'chamber by the passages 9 and 10. See lig 2. A. deliverypassage 8 Which delivers to the valve chamber on the upper side of thepilot valve diaphragm 13 and on the same side thereof as the supplypassage 5. The passage 9 for flashing the pilot opens into the chamber12 on the same side thereof as the supply connections 8, as does alsothe by-pass passage 10, this by-pass passage is preferably controlledwith the regulating valve 14 Which is adjusted to regulate the size ofthe normal pilot llame. When the passage 9 is opened, an additionalsupply of gas is admitted to the pilot to Hash the same. I thereforedesignate this passage as a flashing passage. The valve diaphragms 11and 13 are concavo-convex in general form and are arranged to moveoppositely in closing, so that by connecting a means for producingsuction and pressure to the chamber 12 between the diaphragms the valvesare simultaneously opened. The valve seats 15 and 16, respectively, forthe pilot and main valves preferably project slight-ly into the chamber12, as illustrated. In the structures illustrated in Figs. 2, 3 and 5,the valvesproper 11 and 13 are formed integrally with their diaphragms11 and 13 respectively. The valve 11 is adapted to automatically closeWhile the valve 13 is adapted to remain in either its open or closedpositions until moved or actuated through the diaphragm actuating means.This result is accomplished by the form of the diaphragms. I preferablyaccomplish this by forming the main valve diaphragm with an inwardcurvature, although it may be accomplished by other means. Thisdiaphragm is also preferably concent-rically stepped, as illustrated.

The means for actuating the valves preferably consist of a casing 17having a plun vger seat portion 19 at its lower end, the seat portionbeing preferably tapered. lVithin the chamber is a diaphragm 2O which'isarranged to form a partition across the chamber. On this diaphragm is aplunger 21 having' a stem or linger piece Q2 thereon a1'H ranged throughthe outer end of the casing. The connecting tube 23 preferably opensinto the chamber within the seat portion thereof, so that it is closedby the plunger when the plunger is in its inner position. Thisconnecting tube 23 is connected to the valve casing` and through thepassage 24 to the chamber between the valves. See Fig. S. The-casing 17is provided with vent openings 25 at its outer end to permit easyadjustment of the plunger. I also preferably provide the casing with arelie-f passage 2G? which is controlled by the passage 27, the valvebeing arranged to open outwardly. The valve is held normally on its seatby the spring 2S. See Fig. 1. The advantage of this is to permit theready seating of the plunger in case it is desired to open the valve,that is, the plunger can be moved to its inner position so that thevalves are opened by the suction movement thereof.

In the modified construction shovvn in Fig. 5, the pilot flashingfeature is omitted, so that the main burner valveis all t-hat isrequired. The valve here acts in the same manner as in the structuredescribed in detail.

In the modilied structure shown in Fig. 6 the valve 13 is adapted toclose with instead of against the gas pressure. This valve is preferablytapered and the valve seat 1G is also preferably tapered as shown. Thevalve diaphragm 13 in this structure is also adapted to remain in eitherits open or closed position.

lWy improved valve is comparatively simple in structure and ispreferably made up of parts as is illust-rated in the drawings, forconvenience in manufacture and assembling. As these details of structureform no part of the invention they are not specifically describedherein.

I have illustrated and described my improved valve in the form in whichI have embodied it. I am, however, aware that it .is capable ofconsider-able variation in structural details without departing from myinvention, and I des-ire to be understood as claiming the same broadlyas well as specilically.
